I'm selling this monitor because I'm upgrading to a larger one. I've been using it for about 3 years. I used the back attachments instead of the stand, and it was only used indoors. (The included stand will be included in the packaging.) It was used in a private residence, not an office. As you can see in the photos, there are no noticeable scratches, but please understand that this is a used item. - Brand: I/O DATA - Model Name: EX-LD221DB-B - Voltage: 100V - Size: 21.5 inches - Flat
